You must CHECK YOUR CHILD'S FOOT SIZE prior to selecting the shoe size. Please check our size charts below (there is also more detailed charts at the bottom of the home page), and also remember to measure your child's feet from back of heel to end of the longest toe, select the longest measurement then add 1cm for wriggle room for a snug fit. The shoes are a medium width, so if your child has a wider than average foot then choose a larger size. Always choose a larger rather than smaller shoe.
